The Secure Ethyl Vinyl Acetate (EVA) containers are made with an EVA material that does not contain harmful plasticizers such as DEHP, which can leach into TPN solutions. EVA is more durable for reduced breakage, more stable for improved safety and more transparent for improved admixture inspection. The Secure bags are latex-free and all tubes are made with Non-DEHP Vinyl. More reasons to feel secure. The Secure TPN line of bags is composed of bags that can be filled by various TPN compounders, filled by gravity, or filled with syringes or single-station filling devices. There is a Secure bag for nearly every TPN and IV application.
